Circumstances in which the application is brought
7Mrs Twaddell tendered a bundle of documents obtained on notice to produce and subpoena to the Corporation (exhibit A). There was no objection to the admission of that material into evidence. The Corporation acknowledged at the hearing that the bundle reproduces the Corporation's documents in the order in which that material was produced in response to the notice to produce and the subpoena (T47-48).
8The three decisions of which review is sought are:
(a)the Corporation's decision notified by letter dated 4 January 2011 to cancel Mrs Twaddell's rental rebate retrospectively and to raise a debt of $12,235.79 against her rental account (page 78 of exhibit A);
(b)the Corporation's decision notified by letter dated 17 October 2011 to affirm the original decision (page 106 of exhibit A);
(c)the Corporation's decision made on or about 30 January 2012 not to accept the recommendation of the Housing Appeals Committee made on 12 December 2011 and to affirm the original decision (recorded at page 165 of exhibit A).
9The Corporation's power to grant rental rebate is contained in s 56 of the Housing Act. The power to vary or cancel any rental rebate granted under s 56 is contained in s 57 of the Act. In each case, the power is expressed to arise after "making" (s 56) or "conducting" (s 57) "an investigation under section 58".
10The power to vary or cancel a rebate may be exercised with retrospective operation, in which event the amount of any overpayment can be recovered. Section 57(4) of the Act provides:
(4) If the Corporation reduces or cancels a tenant's rental rebate under this Part with effect from a preceding date, the Corporation may, by notice in writing to the tenant, require the tenant to pay to the Corporation:
(a) an amount equal to any rental rebate or part of a rental rebate received by the tenant on or after the date that the variation or cancellation took effect to which, because of the variation or cancellation, the tenant was not entitled, and
(b) interest (at the rate prescribed under section 101 of the Civil Procedure Act 2005 in respect of unpaid judgments) on any outstanding amount under paragraph (a) from a date specified in the notice, being a date not earlier than the date on which the notice is issued to the tenant.
11A critical issue in the present application is the content of the requirement to conduct an investigation under s 58. That section provides:
58 Investigation of application
(1) The Corporation may make an investigation to determine the weekly income of:
(a) a person who is an applicant for, or a recipient of, a rental rebate under this Part, and
(b) any other resident of the house in which that person resides.
(2) The Corporation may require a person who is an applicant for, or a recipient of, a rental rebate under this Part to produce such evidence as the Corporation thinks fit of the person's weekly income and of the weekly income of any other resident of the house in which that person resides.
*
12It was an agreed premise of the argument before me that the power to cancel the rental rebate was not enlivened unless there had been an investigation within the meaning of that section (see T18.17). The Court of Appeal has recently confirmed the correctness of that premise, whilst also holding that the required investigation need not be confined to the purpose stated in the section (of determining the weekly income of the relevant persons). The Court further held that the considerations relevant to the exercise of the power are not confined to the matters discovered upon such investigation or to matters pertaining to income: see New South Wales Land and Housing Corporation v Navazi [2013] NSWCA 431 at [7] per Barrett JA; at [29], [38] and [47] per Leeming JA; and see [3] per Basten JA.
13Basten JA expressed the tentative view that, since the investigation contemplated under s 58 is directed to determining the weekly income of the relevant persons, whereas "it may readily be envisaged that a person may be ineligible on other grounds", s 58 arguably does not operate in all cases. However, as already noted, it was conceded by the Corporation that it operated in the circumstances of the present case. The present application is accordingly governed by the principle stated by the Court of Appeal in Navazi that the purpose identified in s 58 (of determining the weekly income of the relevant persons) must be a purpose of the investigation, but need not be its sole purpose.
14The decision in Navazi also holds that there is no requirement that the investigation be exhaustive or conclusive. Leeming JA said (at [46]):
The Act leaves all those matters uncircumscribed. Putting to one side an "investigation" where there was no bona fide attempt to obtain information, there is no reason to imply a minimal standard of diligence or success which must be attained before there is an "investigation under section 58".
15Those remarks reveal that, while there is no minimum standard of diligence or success, there must at least be a bona fide attempt to obtain information. His Honour was plainly referring in that context to information on the topic identified in s 58, namely, the weekly income of the relevant persons.
16The event that prompted the Corporation to re-assess Mrs Twaddell's entitlement to a rental rebate was the receipt in May 2010 of anonymous allegations through the Corporation's "fraud and corruption hotline". There does not appear to be any contemporaneous record of those allegations. Two records were forwarded to the Tenant Fraud Unit by email on 24 June 2010 but it is not clear whether those emails were intended to pass on the May allegations or whether they were separate reports by the same or a different complainant (see pages 37-38B of exhibit A). In any event, it is clear enough that the Corporation received an anonymous allegation that Raymond Twaddell had been residing at the premises for four years and that Matthew Mark had been residing there for a period variously referred to as being in the order of one to four months. It was also alleged that Raymond Twaddell had been arrested some time earlier for growing cannabis at the premises (see pages 37 and 65 of exhibit A).
17On 18 June 2010, the Corporation wrote to Mrs Twaddell informing her of the first part of the allegation (that Raymond Twaddell and Matthew Mark had been residing at the premises) and requesting her to attend an interview. The letter referred to the Corporation's power to undertake an investigation in the terms of s 58 of the Act (page 35 of exhibit A).
18Separately, on the same day, the department requested information from the New South Wales Police concerning the allegation that drugs had been found at the premises (page 33 of exhibit A). On 28 June 2010, police responded to that request by providing a statement of facts relating to the arrest of Raymond Twaddell on 11 January 2008 for possession of two cannabis plants in the rear yard of the premises. The statement of facts recorded that Raymond Twaddell admitted ownership of the cannabis plants.
19Mrs Twaddell attended the Corporation for an interview on 6 July 2010. Exhibit A does not contain any contemporaneous note of that interview. A summary of the interview contained in a memorandum dated 25 August 2010 records discussion only of the issue whether Raymond Twaddell and Matthew Mark were in fact residing at the premises, as alleged by the anonymous caller (page 65 of exhibit A).
20On 7 July 2010, Ms Rachel Weir on behalf of the Corporation requested further information from Mrs Twaddell. The request was made in the following terms:
Information to confirm Matthew Mark's residential address. Bank statements, driver's licence or proof of rental details.
Information to confirm Raymond Twaddell's residential address. Bank statements, proof of rental details, copy of lease.
21The letter sought no information as to the income of either man.
22As already noted, the Corporation acknowledges that the documents in exhibit A replicate the original bundle of material as produced by the Corporation on subpoena in these proceedings. The sequence in which that material appears suggests that the only information in relation to Raymond Twaddell and Matthew Marks provided by Mrs Twaddell in response to Ms Weir's letter was the material at pages 45 to 56 of exhibit A. That conclusion is reinforced by the contents of the memorandum dated 25 August 2010 which lists the "requested documentary evidence provided" (pages 65 to 66 of exhibit A). I am satisfied that the material provided by Mrs Twaddell in response to Ms Weir's request was as follows:
(a)a handwritten letter by Raymond Twaddell. Mr Twaddell stated "I will not deny that I do visit my children everyday, as you could well understand. But I do not live there." He explained that the previous three to four years had been tumultuous and that, during that time, he had had multiple residences including three specified addresses at Eaglevale, Ingleburn and Ambarvale and "a few other places along the way". Mr Twaddell explained that he worked locally, which made visiting easier. He said that, since he had not had a stable place of residence following the breakdown of his marriage, it had been convenient to keep the Housing Commission premises as his address.
Mr Twaddell also acknowledged that he had been present at the premises when police executed a search warrant and seized two marijuana plants. He said "I told the police that this was my place of residence to protect Tanya and the kids fearing they would be evicted for my stupidity".
Mr Twaddell also volunteered that Mrs Twaddell had asked him to stay at her place on Tuesday nights "to watch the kids" as she had recently started working on those nights at Woolworths (pages 45 and 46 of exhibit A);
(b)a letter dated 13 July 2010 from the occupant of the Ingleburn address stating that Mr Twaddell had been living with him for the past three months (page 47 of exhibit A);
(c)a letter from Steven and Susan Marks to "certify" that Mr Twaddell had lived at the Eaglevale address with them in 2008 prior to Mr Marks having a stroke (page 48 of exhibit A);
(d)a letter from the occupant of the Ambarvale address stating that Mr Twaddell lived with them for 20 months (undated) (page 49 of exhibit A);
(e)a letter from Mrs Twaddell providing details consistent with the other correspondence (page 50 of exhibit A);
(f)a letter from Steven and Susan Marks to "certify" that Matthew Marks was then living with them at the Eaglevale address (page 51 of exhibit A);
(g)a Telstra bill dated 10 June 2010 addressed to Mr M J Marks at the Eaglevale address (page 52 of exhibit A);
(h)a notice of assessment from the Australian Taxation Office dated 9 September 2009 addressed to Mr Matthew Marks at the Eaglevale address (page 53 of exhibit A);
(i)a letter from the Australian Taxation Office to Mr Twaddell dated 28 April 2008 addressed to the Eaglevale address (page 54 of exhibit A);
(j)two superannuation letters dated 19 March 2008 and 4 December 2009 addressed to Mr Twaddell at a different Ambarvale address (pages 55 and 56 of exhibit A);
23The different Ambervale address identified in the last two letters listed above later assumed some significance. That address will be referred in this judgment as the second Ambarvale address
24The only information relating to the income of either Raymond Twaddell or Matthew Marks contained in that material is the notice of assessment addressed to Matthew Marks. It is clear that the notice was supplied to the Corporation in response to Ms Weir's request for information to confirm Matthew Marks' residential address. The notice relates to the year ending 30 June 2009, which is before the period identified by the anonymous caller as the period during which Mr Marks allegedly resided at Mrs Twaddell's premises.
25On 3 August 2010, Mrs Twaddell made a fresh rent subsidy application which included the information that on 10 June 2010 she had started work (pages 57 to 60 of exhibit A). The application attached two pay slips. The copies reproduced in exhibit A at pages 61 and 62 are difficult to read but appear to be consistent with her having worked something in the order of four to seven hours per week for the period disclosed in the application.
26A memorandum prepared by an investigator of the tenant fraud unit dated 25 August 2010 set out a careful and considered analysis of that material and recorded the conclusion that the evidence provided by the tenant was stronger than the evidence held by the Corporation (pages 65 to 67 of exhibit A). The memorandum made no recommendation for further action by the tenant fraud unit. That appears to have disposed of any suggestion of criminal proceedings.
27Ms Weir then prepared a memorandum dated 24 September 2010 recommending that Mrs Twaddell's rental subsidy nonetheless be cancelled from 19 November 2006 to 29 August 2010 (pages 69 to 70 of exhibit A). The memorandum calculated an estimated debt of $20,029.20.
28The memorandum appears to have been annotated by the team leader on 9 November 2010 with a recommendation "that no further action in this matter be warranted". It is not clear whether that recommendation was confined to the issue of any criminal prosecution or whether it also comprehended the issue of rental rebate.
29In any event, on 12 November 2010, Ms Gemma Cooney evidently formed a different view. She wrote (in an email):
Following a review of the reports and evidence provided I believe HNSW is within its rights to challange (sic) the integrity of the evidence provided, as I have determined that one of the addresses provided as an alternative address for Mr Twaddell is also a HNSW property and that Mr Twaddell was never included or approved at that address as an additional occupant.
HNSW will calculated the outstanding debt for dates that evidence supports his occupancy (approximately $9,500) and will proceed will proceed with action at the CTTT to recoup the outstanding debt or seek termination. Staff will also interview the occupant at [the second Ambarvale address] concerning Mr Twaddell's unauthorised occupancy for the period between 08/09 to determine the validity of the tenant's statement, and if confirmed will calculate the debt owing to HNSW by the tenant at [the second Ambarvale address], if the tenant subsequently denies Mr Twaddell resided at the address action may be taken against the tenant for providing a false statement to HNSW, and the debt will then be included on to Ms Twaddell's rental account.
30Mr Smith, who appeared with Ms McWilliam for the Corporation, submitted that Ms Cooney's email set out above should be regarded as the record of the decision to cancel Mrs Twaddell's rental rebate. The only further consideration following that email was a series of exchanges about the calculation of the debt, including the following email dated 4 January 2011 by Ms Weir:
Genene, I have completed the fraud and done the account adjustments for this tenancy. We now have to investigate [the second Ambarvale address] for non disclosure for Raymond Twaddell for between March 2008 until January 2010, this will have to be done when we get another CSO, if we can't prove the non disclosure for [the second Ambarvale address] then we will have to put the debt on [Mrs Twaddell's address].
31Acknowledging that I must not distract myself with the merits of the decision under review, it is difficult to understand the basis for Ms Weir's conclusion that Raymond Twaddell had lived at the second Ambarvale address between March 2008 and January 2010. Those dates appear to have been drawn from the two superannuation letters directed to Mr Twaddell at that address (pages 55 and 56 of exhibit A). However, within the material provided at the same time, the Corporation had a document dated 28 April 2008 directed to Mr Twaddell at the Eaglevale address, the home of Mrs Twaddell's parents, and a letter from them stating that he was living with them in 2008. Mr Twaddell had never put the second Ambarvale address forward as an address at which he lived during that time.
32As already noted, the Corporation submitted that the record of the decision to cancel the rental rebate was Gemma Cooney's email dated 12 November 2010 (part of page 76 of exhibit A). Mr Robinson SC, who appeared with Ms Gumbert for Mrs Twaddell, submitted that the relevant document recording the decision was the letter dated 4 January 2011 from Ms Weir to Mrs Twaddell (page 78 of exhibit A). In that letter, Ms Weir wrote:
As you are aware, Housing NSW has received information that:
Your husband Raymond Twaddell had been residing at your premises between November 2006 and March 2008.
Housing NSW was also provided information that your husband provided your address as his residential address to the RTA between 2004 to 2010.
Housing has been provided with information that your husband is currently residing at your premises and has been since January 2010.
33The letter stated that, after considering all the circumstances, it had been decided that Mrs Twaddell had failed to disclose the matters recorded in the first and third bullet points and that, "as a result", her rent subsidy had been re-assessed.
34The letter continued:
Due to your subsidy reassessment, a total debt of $12,235.79 has been placed on your rental account. As at 04 January 2011, your current balance is now $12,418.42 in debit.
